Answer:

4. c) They result in production of diffusible second messengers

Explanation:

G-protein coupled receptors (GPCR) and steroid hormone receptors have common in the way that both result in the production of diffusible second messengers into the cytosol for further initiation of signal transduction pathways in the target cell. Hence option (c) is the correct answer.

Answer:

c) They result in production of diffusible second messengers.

Explanation:

In G protein coupled receptors and steroid hormone receptors, when a ligand binds to these receptors, it activates one or more signal transduction systems, which initiate different cascades of events that alter the concentration of intracellular second messengers which stimulates other cascade of reactions.

Evaluate the lab and data collected. What type of transport occurred in this lab? Explain your answer, including evidence from y
andreev551 [17]

To know what type of transport occurred the lab and collected data are needed. As they are not present an explanation of the different transport's types, will be given.

Water, proteins, ions, and molecules of different sizes can pass through the cell membrane using different types of transports. The transport that each molecule uses depends on the concentration, size, and polarity.

We can classify the types of transport as active and passive.

Passive transport is the one that does not need energy to happen since the molecules move from a place of high concentration to a one of lower concentration. In this group, we have:

  • Simple diffusion: small molecules in high concentration on one side of the membrane; move to the other side due to the difference in concentration.
  • Osmosis: water passes through the membrane from a place of low concentration of molecules to one of high concentration. Water moves inside or outside the cell to valance the concentration of solutes on both sides of the membrane.
  • Facilitated diffusion: uses proteins to transport large molecules, ions, or hydrophobic molecules from one side to the other. In this type of transport, we have proteins that form channels so those hydrophobic molecules can pass through the lipid membrane, and carrier proteins, which binds to a specific molecule changing their shape and transporting the molecule.

Active transport needs the<em> energy</em> to transport molecules; since it goes against the gradient's concentration. In this group, we have:

  • Sodium-Potassium pump: uses ATP to move sodium outside the cell and potassium to the inside. The ions with this transport go to where they are most concentrated.

In conclusion, there are different types of transport; they depend on the concentration or type of molecule. To find out what mechanism of transport occurred in the lab, look at the components of the experiment and analyze which of these transports could be present.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two
Oduvanchick [21]
Option A is correct. After making a punnet square, we can see that the genotypic ratio would be 1:2:1, being 25% dominant, 25% recessive and 50% heterozygous. However, we are asked for the phenotypic trait percentage. The phenotypic ration is 3:1, with 75% polka dotted tail (dominant gene active) and 25% solid tail (recessive gene active).

Would you withdraw CSF if the needle were accidentally inserted into the epidural space instead of the subarachnoid
castortr0y [4]

Answer: No. You would not withdraw CSF if the needle is in the epidural space.

Explanation: There are 3 spaces that cover the spinal cord, which are epidural, subdural and subarachnoid spaces. The epidural space is the outer most space while the subarachnoid space is the inner most space. CSF flows from the brain where it is produced to the spinal cord. In the spinal cord it flows only in the subarachnoid space. Thus you would not be able to withdraw CSF if the needle is in the epidural space.
